He embraced Islam in the year 7 AH a year before his father did, Amr ibn al-'As, the prophet Muhammad used to show preference to Abd Allah ibn 'Amr due to his knowledge. He was one of the first companions to write down the Hadith, after receiving permission from prophet Muhammad to do so. Abu Huraira used to say that Abd Allah ibn 'Amr was more knowledgeable than him.[3][4]

His work Al-Sahifah al-Sadiqah remained in his family and was used by his grandson 'Amr ibn Shu'ayb. Ahmad ibn Hanbal incorporated the whole of the work of Abd Allah ibn 'Amr in his voluminous book Musnad Ahmad ibn Hanbal thereby covering up for the missing Al-Sahifah al-Sadiqah which was written in the days of Prophet Muhammad.[4]

Amr was a shrewd, highly intelligent man who belonged to the nobility of the Quraysh and he fought with the Quraysh against Islam in several battles.

Sahaba
–
The term aṣ-ṣaḥābah refers to the companions, disciples, scribes and family of the Islamic prophet Muhammad. This form is definite plural, the singular is masculine sahabi. Later scholars accepted their testimony of the words and deeds of Muhammad, the testimony of the companions, as it was passed down through trusted chains of narrators, was the basis of the developing Islamic tradition. The most widespread definition of a companion is someone who met Muhammad, believed in him and died as a Muslim. ”Anyone who died after rejecting Islam and those who saw him but held off believing in him until after his passing are not considered Sahaba but Tabiin. In their view, the Quran has outlined a high level of faith as one of the qualities of the Sahabah. Hence, they admit to this list only those individuals who had contact with Muhammad, lived with him. This view has implications in Islamic law since narrations of Muhammad transmitted through the Sahabah acquire a status of authenticity. Lists of prominent companions usually run to 50 or 60 names, the book entitled Istîâb fî marifat-il-Ashâb by Hafidh Yusuf bin Muhammad bin Qurtubi consists of 2,770 biographies of male and 381 biographies of female Sahabah. According to an observation in the book entitled Mawâhib-i-ladunniyya, a number of persons had already converted to Islam by the time Muhammad died. There were 10,000 by the time Mecca was conquered and 70,000 during the Battle of Tabouk in 630. Some Muslims assert that they were more than 200,000 in number, indeed, He was to them Kind and Merciful. In Islam, there are three types of Sahabah, The people who were Muslims at the time of Badr, but those who believed and did not emigrate - for you there is no guardianship of them until they emigrate. And if they seek help of you for the religion, then you must help, and Allah is Seeing of what you do. Quran, sura 8, ayah 72 And hold firmly to the rope of Allah all together and do not become divided. And remember the favor of Allah upon you - when you were enemies and He brought your hearts together and you became, by His favor, and you were on the edge of a pit of the Fire, and He saved you from it. Thus does Allah make clear to you His verses that you may be guided, Muhammad is the Messenger of Allah, and those with him are forceful against the disbelievers, merciful among themselves. You see them bowing and prostrating, seeking bounty from Allah and their mark is on their faces from the trace of prostration. That is their description in the Torah, Allah has promised those who believe and do righteous deeds among them forgiveness and a great reward. The people who were Muslims before victory at Mecca and went into exile and they are also high in degree, especially those who were present at Hudabiyah

Islam
–
Islam is an Abrahamic monotheistic religion which professes that there is only one and incomparable God and that Muhammad is the last messenger of God. It is the worlds second-largest religion and the major religion in the world, with over 1.7 billion followers or 23% of the global population. Islam teaches that God is merciful, all-powerful, and unique, and He has guided mankind through revealed scriptures, natural signs, and a line of prophets sealed by Muhammad. The primary scriptures of Islam are the Quran, viewed by Muslims as the word of God. Muslims believe that Islam is the original, complete and universal version of a faith that was revealed many times before through prophets including Adam, Noah, Abraham, Moses. As for the Quran, Muslims consider it to be the unaltered, certain religious rites and customs are observed by the Muslims in their family and social life, while social responsibilities to parents, relatives, and neighbors have also been defined. Besides, the Quran and the sunnah of Muhammad prescribe a comprehensive body of moral guidelines for Muslims to be followed in their personal, social, political, Islam began in the early 7th century. Originating in Mecca, it spread in the Arabian Peninsula. The expansion of the Muslim world involved various caliphates and empires, traders, most Muslims are of one of two denominations, Sunni or Shia. Islam is the dominant religion in the Middle East, North Africa, sizable Muslim communities are also found in Horn of Africa, Europe, China, Russia, Mainland Southeast Asia, Philippines, Northern Borneo, Caucasus and the Americas. Converts and immigrant communities are found in almost every part of the world, Islam is a verbal noun originating from the triliteral root s-l-m which forms a large class of words mostly relating to concepts of wholeness, submission, safeness and peace. In a religious context it means voluntary submission to God, Islām is the verbal noun of Form IV of the root, and means submission or surrender. Muslim, the word for an adherent of Islam, is the active participle of the verb form. The word sometimes has connotations in its various occurrences in the Quran. In some verses, there is stress on the quality of Islam as a state, Whomsoever God desires to guide. Other verses connect Islām and dīn, Today, I have perfected your religion for you, I have completed My blessing upon you, still others describe Islam as an action of returning to God—more than just a verbal affirmation of faith. In the Hadith of Gabriel, islām is presented as one part of a triad that also includes imān, Islam was historically called Muhammadanism in Anglophone societies. This term has fallen out of use and is said to be offensive because it suggests that a human being rather than God is central to Muslims religion

Muhammad
–
Muhammad is the prophet of Islam. From a secular historical perspective he was a religious, political, from an Islamic perspective, he was Gods Messenger sent to confirm the essential teachings of monotheism preached previously by Adam, Abraham, Moses, Jesus, and other prophets. He is viewed as the prophet of God in all branches of Islam. Muhammad united Arabia into a single Muslim polity and ensured that his teachings, practices, born approximately 570 CE in the Arabian city of Mecca, Muhammad was orphaned at an early age, he was raised under the care of his paternal uncle Abu Talib. Muhammad gained few early followers, and met hostility from some Meccan tribes, to escape persecution, Muhammad sent some followers to Abyssinia before he and his followers migrated from Mecca to Medina in the year 622. This event, the Hijra, marks the beginning of the Islamic calendar, in Medina, Muhammad united the tribes under the Constitution of Medina. In December 629, after eight years of intermittent conflict with Meccan tribes, Muhammad gathered an army of 10,000 Muslim converts, the attack went largely uncontested and Muhammad seized the city with little bloodshed. In 632, a few months after returning from the Farewell Pilgrimage, he fell ill, before his death, most of the Arabian Peninsula had converted to Islam. The revelations, which Muhammad reported receiving until his death, form the verses of the Quran, regarded by Muslims as the Word of God and around which the religion is based. Besides the Quran, Muhammads teachings and practices, found in the Hadith and sira literature, are upheld by Muslims. The name Muhammad means praiseworthy and appears four times in the Quran, Muhammad is sometimes addressed by designations deriving from his state at the time of the address, thus he is referred to as the enwrapped in Quran 73,1 and the shrouded in Quran 74,1. In Sura Al-Ahzab 33,40 God singles out Muhammad as the Seal of the Prophets, the Quran also refers to Muhammad as Aḥmad more praiseworthy. The name Abū al-Qāsim Muḥammad ibn ʿAbd Allāh ibn ʿAbd al-Muṭṭalib ibn Hāshim, begins with the kunya Abū, the Quran is the central religious text of Islam. Muslims believe it represents the words of God revealed by the archangel Gabriel to Muhammad, the Quran, however, provides minimal assistance for Muhammads chronological biography, most Quranic verses do not provide significant historical context. An important source may be found in the works by writers of the 2nd. These include the traditional Muslim biographies of Muhammad, which additional information about Muhammads life. The earliest surviving written sira is Ibn Ishaqs Life of Gods Messenger written c.767 CE, although the work was lost, this sira was used verbatim at great length by Ibn Hisham and Al-Tabari. Another early history source is the history of Muhammads campaigns by al-Waqidi, many scholars accept the earliest biographies as accurate, though their accuracy is unascertainable

Arabic
–
Arabic is a Central Semitic language that was first spoken in Iron Age northwestern Arabia and is now the lingua franca of the Arab world. Arabic is also the language of 1.7 billion Muslims. It is one of six languages of the United Nations. The modern written language is derived from the language of the Quran and it is widely taught in schools and universities, and is used to varying degrees in workplaces, government, and the media. The two formal varieties are grouped together as Literary Arabic, which is the language of 26 states. Modern Standard Arabic largely follows the standards of Quranic Arabic. Much of the new vocabulary is used to denote concepts that have arisen in the post-Quranic era, Arabic has influenced many languages around the globe throughout its history. During the Middle Ages, Literary Arabic was a vehicle of culture in Europe, especially in science, mathematics. As a result, many European languages have borrowed many words from it. Many words of Arabic origin are found in ancient languages like Latin. Balkan languages, including Greek, have acquired a significant number of Arabic words through contact with Ottoman Turkish. Arabic has also borrowed words from languages including Greek and Persian in medieval times. Arabic is a Central Semitic language, closely related to the Northwest Semitic languages, the Ancient South Arabian languages, the Semitic languages changed a great deal between Proto-Semitic and the establishment of the Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include, The conversion of the suffix-conjugated stative formation into a past tense, the conversion of the prefix-conjugated preterite-tense formation into a present tense. The elimination of other prefix-conjugated mood/aspect forms in favor of new moods formed by endings attached to the prefix-conjugation forms, the development of an internal passive. These features are evidence of descent from a hypothetical ancestor. In the southwest, various Central Semitic languages both belonging to and outside of the Ancient South Arabian family were spoken and it is also believed that the ancestors of the Modern South Arabian languages were also spoken in southern Arabia at this time. To the north, in the oases of northern Hijaz, Dadanitic and Taymanitic held some prestige as inscriptional languages, in Najd and parts of western Arabia, a language known to scholars as Thamudic C is attested

Ahmad ibn Hanbal
–
Additionally, Ibn Hanbal is also honored as the founder of the Hanbali school of Sunni jurisprudence, which is one of the four major orthodox legal schools of Sunni Islam. The fourteenth-century hadith master al-Dhahabi referred to Ibn Hanbal as the true Shaykh of Islām and leader of the Muslims in his time, in the modern era, Ibn Hanbals name has become controversial in certain quarters of the Islamic world. In this connection, scholars have cited Ibn Hanbals own support for the use of relics as simply one of important points upon which the theologians opinions diverged from those of Wahhabism. Ahmad ibn Hanbals family was originally from Basra, Iraq, and his father was an officer in the Abbasid army in Khurasan and later settled with his family in Baghdad, where Ahmad was born in 780 CE. Ibn Hanbal had two wives and several children, including a son, who later became a judge in Isfahan. Ahmad Ibn Hanbal studied extensively in Baghdad, and later traveled to further his education and he started learning jurisprudence under the celebrated Hanafi judge, Abu Yusuf, the renowned student and companion of Imam Abu Hanifah. After finishing his studies with Abu Yusuf, ibn Hanbal began traveling through Iraq, Syria, Ibn al-Jawzi states that Imam Ahmad had 414 Hadith masters whom he narrated from. With this knowledge, he became an authority on the hadith, leaving an immense encyclopedia of hadith. After several years of travel, he returned to Baghdad to study Islamic law under Al-Shafii, unlike the other three schools of Islamic jurisprudence, the Hanbali madhab remained largely traditionalist or Athari in theology. In addition to his enterprises, ibn Hanbal was a soldier on the Islamic frontiers and made Hajj five times in his life. Ahmad Ibn Hanbal died on Friday,12 Rabi-ul-I,241 AH/2 August,855 at the age of 74-75 in Baghdad, Iraq. Historians relate that his funeral was attended by 800,000 men and 60,000 women, Ibn Hanbal was famously called before the Inquisition or Mihna of the Abassid Caliph al-Mamun. Al-Mamun wanted to assert the authority of the Caliph by pressuring scholars to adopt the Mutazila view that the Quran was created rather than uncreated. Due to his refusal to accept Mutazilite authority, ibn Hanbal was imprisoned in Baghdad throughout the reign of al-Mamun, in an incident during the rule of al-Mamuns successor, al-Mutasim, ibn Hanbal was flogged to unconsciousness. However, this caused upheaval in Baghdad and al-Mamun was forced to release ibn Hanbal, after al-Mu’tasim’s death, al-Wathiq became caliph and continued his predecessors policies of Mutazilite enforcement and in this pursuit, he banished ibn Hanbal from Baghdad. It was only after death and the ascent of his brother al-Mutawakkil, who was much friendlier to the more traditional Sunni beliefs. Ibn Hanbals principal doctrine is what came to be known as traditionalist thought. He did, however, believe that it was only a few who were properly authorized to interpret the sacred texts

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker
